Application filed April 26,

To all UP/7107771 it may concern:

Be it known that l, LEE S. GIIADW'ICK, a citizen of the United States. residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Means for Connecting l-lydrocarbon-Burners to Supply-Pipes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to improvements in hydrocarbon burners of the sort that are communicatively connected to and are supported solely by a fuel supply pipe, an example of such a burner being found in the patent to Jeavons, No. 1,039,950, issued October 1, 1912. More particularly, the invention relates to improved means for communicatively connecting the burner to the supply pipe and for securing or clamping the burner and pipe together so that the former is held against turning with respect to the latter.

The objects of the invention are to provide a leak proof connection between the burner and pipe that is extremely simple, and consequently cheap of production; to provide a connection of the aforesaid na ture that will effectually lock the burner against turning with respect to the pipe; to provide a construction wherein the original thickness of the pipe is maintained at the zone of its communicative conncction with the burner (which is not the case in prevailing constructions of this sort); to associate with the supply connection certain clamping elements which coact with the connection to firmly clamp the burner to the pipe, and wherein a constant tension exists when the parts are completely assembled, thus assuring a permanent clamping action; to provide means for accomplishing the immediately foregoing object in a very simple and economical manner; and to produce a construction through which the above objects are attained, and which may be very conveniently and quickly assembled and disassembled.

In the accompanying drawings- Figure 1 is a central vertical section through the lower portion of a hydrocarbon burner connected to a supply pipe in accordance with my invention; Fig. 2 is a perspective view of the elbow and packing washer shown in Fig. 1; Fig. 3 is a frag- Specification of Letters Patent.

mentary perspective view of the pipe, showing the seat for the washer and elbow of the preceding figure; Figs. 1, 5, and 6 correspond, respectively, to Figs. 1, 2, and 3, and show a slightly modified form of elbow and pipe seat; Fig. 7 is a central vertical section through a connection similar to that of Fig. and wherewith certain clamping elements are associated; Fig. 8 is a perspective view of the clamping elements of Fig. 7 9 is a perspective view of, the clamp used in the forms of my invention illustrated in Figs. 1 and i; and Fig. 10 is a perspective view of a locating fork for the side of the burner opposite the supply fitting.

The style of burner with which my invention is used is well known to those familiar with the art, the same comprising an inner and an outer wick tube that are spaced apart in concentric relation and connected together and sealed against leakage at their lower ends to produce an annular chamber for the reception of a wick, the burner being referred to, generally, in the drawings, by the reference letter A, and the supply pipe to which it is connected, by the reference letter B. i

It will be found upon referring to the Jeavonss patent, mentioned toward the beginning of this specification, that the jointbetween the supply connection or elbow of the burner, and the supply pipe, is of quite a complicated nature. Prior to my present invention, to the best of my knowledge, connections were made between the supply connection of the burner and the supply pipe according to the method shown in this patent, to wit, by cutting a flat seat upon the supply pipe surrounding the hole through which the burnercommunicated with the pipe, and placing some sort of packing member between the pipe and the supply connection. This resulted in reducing the thickness of the pipe materially in the vicinity of the hole, thus weakening the pipe. Also, because of the contour of the pipe, the seat was of very slight lateral extent, and consequently had very little effect in holding the burner against turning with respect to the pipe.

It is my intention to overcome this di1'ii culty by pressing a seat in the pipe, as illustrated (in one form) in Figs. 1 and 3. By thus pressing the seat in the pipe, the seat and in the angle between the shoulder and the extension, there is formed a groove 52 into which a quantity of the washer 50 is forced, when the parts are bound together by the clamp C, presently to be described. The outer wall of the groove 52 is inclined upwardly and inwardly toward the extension 3 so as to exert an inward force upon the portion of the washer which occupies the groove, thus causing the washer to firmly hug the extension and more effectually seal the joint against leakage.

The clamp C is constructed of a strap or band which is split beneath the pipe, and the screw 56 passes through an aperture in the central portion of the strap, the ends of the strap being soldered, or otherwise so cured to the underneath side of the pipe, thus effectually holding the burner against an 'ular movement with res met to the )l')@. o l

The burner is held a ainst swingin lat- O k I orally in a horizontal plane by the locating fork a4.

In Figs. 4 and 6 I have shown a tapered seat in the pipe B that is obviously simpler to produce by a pressing operation than the straight seat illustrated in Figs. 1 and For use in connection with this tapered seat I employ the elbow shown in perspective in Fig. 5, and in central section in Fig. the only difference between this and the elbow shown in Figs. 1 and 2 being in the angular relation of the shoulder 57, with respect to the'axis of the extension 3 such angle conforming to the angular inclination or ta per of the scat foru'ied to the pipe.

The clamp G is employed in connection with this form of my invention, as in the case preceding.

In the form of my invention illustrated in Figs. 7 and 8, I employ a plate 60 that is attached to the burner adjacent the supply connection and extends outward along the upper side of the supply pipe, the plate having an opening through which the supply connection may extend and enter the aperture of the pipe. The plate terminates, at its outer end, in bearing ortions (31 that are forced, by the clamp G, into contact with the upwardly facing abutment portions 62 of a saddle G3 that embraces the upper side of the supply pipe and is soldered or otherwise secured thereto. Thus, the abutment portions of the saddle are, in effect, lateral projections of the supply pipe, and the cooperating portions of the plate 60 exert a downward thrust thereon when the clamp C is rendered effective. This construction very securely holds the burner against turning with respect to the pipe.

The locating fork 44:, hereinbefore generally referred to, may have one or both of its branches provided with a set screw 65. In such a case, the end of the branch is twisted through about 90 from the plane of the body portion of the fork, and tapped for the reception of the screw 65. Preferably, the screw reposes slightly below the horizontal center of the pipe, so that it will create somewhat of a wedging action when screwed in against the pipe, functioning to draw the burner firmly down against the pipe, at the same time making the with drawal of the fork from the pipe practically impossible.

When opposed set screws are employed, the burner may be adjusted transversely of the pipe in either direction by loosening one screw and setting up on the other, the fork being made sufficiently wide, in this event, to allow for such adjustment.

To afford sufficient thread bearing for the screw 56 associated with clamp C, I employ a nut 56 which is shown as a square nut of standard type, and the nut. is confined between the side branches of the strap or band 55 against turning when the screw is screwed down against the fitting 1.

Having thus described my invention, what I claim is:
